Code review comment for lp:~divmod-dev/divmod.org/logdatetimestart-patch-848342

I get three pyflakes warnings in test_web.py:

Mantissa/xmantissa/test/integration/test_web.py:13: 'http' imported but unused
Mantissa/xmantissa/test/integration/test_web.py:654: local variable 'cookies' is assigned to but never used
Mantissa/xmantissa/test/integration/test_web.py:702: local variable 'cookies' is assigned to but never used

Only the first of these is directly related to your changes, but I guess you might as well fix the other two while you're touching that file.

Once those are fixed, this looks good to merge, thanks!
